1. 請將解答第二行改成 = [┐(┐p v q) v ┐(┐q v r )] v (┐p v r) = (p ^ ┐q) v [(q ^ ┐r) v (┐p v r)] = (p ^ ┐q) v [q v (┐p v r)] ^ [┐r v (┐p v r)] = (p ^ ┐q) v [(q v ┐p v r) ^ 1] = (p ^ ┐q) v q v (┐p v r) = [(p v q) ^ (┐q v q)] v (┐p v r) = (p v q) v (┐p v r) = p v ┐p v q v r = 1

= [┐(┐p v q) v ┐(┐q v r )] v (┐p v r)
= (p ^ ┐q) v [(q ^ ┐r) v (┐p v r)]
= (p ^ ┐q) v [q v (┐p v r)] ^ [┐r v (┐p v r)]
= (p ^ ┐q) v [(q v ┐p v r) ^ 1]
= (p ^ ┐q) v q v (┐p v r)
= [(p v q) ^ (┐q v q)] v (┐p v r)
= (p v q) v (┐p v r)
= p v ┐p v q v r
= 1
2. 你說的沒錯
